I can hardly open any of my windows or my sun roof without my cabin reverberating obnoxiously loud. I recently noticed that the back cover that seals the cabin from the trunk space is oscillating up and down. Anyone have this problem? Any ideas why this is happening or what I can do about it?

Thanks!

I get this low pitched echo really loud also but just if I open my sunroof all the way back. It only goes away when I open any window just a crack.

 

You're getting a pressure oscillation from the wind running over the sunroof. I've had it in other cars. As you said, it goes away when you crack the rear windows OR you can try closing the sunroof just a little...sometimes that reduces the pressure and vibration.

 

Looks like we all have the same problem. It is surprising to think that Audi would overlook this problem, makes me think there is a way to correct it. Hmmmm. Maybe an external wind shield to guide air over the moonroof?
